Should you sand between spray paint coats?
Spray paint typically has a sheen that, when dry, reflects light and emphasizes any surface imperfections, including scratches, dents and nicks. So, before spraying on the final coat of paint, you must sand the surface smooth and then apply at least two primer coats. And be sure to sand between each coat.
